Greg, here a few suggestions of where to look for those chips.
Shop with Jeff, Jackpot Auctions, Bobby Guns, Steve Zacchi, Andy Hughes, also The Chip Board
has listings of people wanting to sell things. Shop with Jeff and Jackpot Auctions, are 2 auction sights where you bid on chips. I suggested these, because Chris and I have dealt with them, and they are reputable, and they know the chips pretty well. Dawn
